+ The bottom left part of the <dfn>Plugin Selector</dfn> is used to filter the listed
+ plugins.

+<p>
+ The center <dfn>Filter</dfn> column allows to show only some of the plugins, based
+ on what they are, their properties, format, creator...
+</p>
+<p>
+ Moreover, direct text search are available in the the Search text-field
+ on the bottom left. Only the plugins that match <em>all</em> the search terms
+ (space separated) will show up in the upper list.
+</p>
+<p>
+ This textual search can be matched against Name and/or Tags by checking
+ the relevant momentary buttons under the search field.

+<h2>Tags</h2>
+
+<p>
+ Tags are text labels that can be used to mark a plugin. They are totally
+ free in their content, allowing the user to mark a plugin with whatever
+ info is relevant to him, but cannot include spaces (as spaces are used
+ to separate tags) or special characters except dashes, colons and underscores.
+</p>
+<p>
+ Adding or removing tags is as simple as editing the <dfn>Tags for Selected Plugin</dfn>
+ field while the targeted plugin is selected.
+</p>
+<p>
+ Ardour comes with a large selection of tags for provided or usual plugins,
+ that are used by default but can be modified at will. It is possible to
+ go back to this "standard" tagging for a plugin by clicking the
+ <kbd class="menu">Reset</kbd> button.
